Over time the house laws were amended, and in the late Russian Empire the laws governing membership in the imperial house, succession to the throne and other dynastic subjects were divided, some being included in the Fundamental Laws of the Russian Empire and others in the Statute of the Imperial Family (codification of 1906, as amended through 1911).[2]

Nonetheless, legally, Tatiana Konstantinovna's marriage was morganatic.[3] It was, in fact, the first marriage in the dynasty conducted in compliance with the Emperor’s formal decision not to accept as dynastic the marriages of even the most junior Romanovs—those that bore only the title of prince/princess—with non-royal partners. According to "Always A Grand Duke", the 1933 memoir of Nicholas II’s brother-in-law, Grand Duke Alexander Mikhailovich (published in New York, by Farrar and Rinehart, Inc.), concern about the eventual marriages of cadet Romanovs so troubled the senior grand dukes that Alexander approached the Emperor about relaxing the requirement that all dynasts marry partners "possessing corresponding rank" enshrined in article 188 of the Pauline Laws, but was rebuffed. The grand dukes then officially petitioned the Emperor through a commission chaired by Grand Duke Nicholas Nikolayevich of Russia, requesting that a new category of dynastic marriages be recognized, to consist of Imperial princes and princesses entitled, with specific Imperial consent, to marry persons of non-royal blood yet retaining the right to transmit to the issue thereof eligibility to inherit the throne. The Emperor’s response was issued formally on 14 June 1911 in the form of a memorandum from the Minister of the Imperial Court, Baron Vladimir Frederiks:[4]

The Lord Emperor has seen fit to permit marriages to persons not possessing corresponding rank of not all Members of the Imperial Family, but only of Princes and Princesses of the Blood Imperial...Princes as well as Princesses of the Blood Imperial, upon contracting a marriage with a person not possessing corresponding rank, shall personally retain the title and privileges which are theirs by birth, with the exception of their right to succession from which they shall have abdicated before entering the marriage. In relation to the categorization of the marriages of Princes and Princesses of the Blood Imperial, the Lord Emperor has seen fit to recognize only two categories in these marriages: (a) equal marriages, i.e. those contracted with persons belonging to a Royal or Ruling House, and (b) unequal marriages, i.e. those contracted with persons not belonging to a Royal or Ruling House, and will not recognize any other categories.

As promised in this communiqué (the so-called "Frederiks Memorandum"), the Emperor proceeded to legalize authorized marriages of imperial Romanovs below grand ducal rank to persons who lacked "corresponding rank". Such marriages had been altogether banned, rather than deemed morganatic, by Alexander III’sukase #5868 on 23 March 1889. But ukase #35731/1489, issued on 11 August 1911, amended the 1889 ban with the words, "Henceforth no grand duke or grand duchess may contract a marriage with a person not possessing corresponding rank, that is, not belonging to a Royal or Ruling house."

Both the 1889 and 1911 decrees were addenda to article 188 of the Pauline laws (re-codified as article 63 of the Imperial Family Statute). Left intact, however, was that original statute: "A person of the Imperial family who has entered into a marriage alliance with a person not possessing corresponding rank, that is, not belonging to a Royal or Ruling House, cannot pass on to that person, or to any posterity that may issue from such a marriage, the rights which belong to the Members of the Imperial family."

Also remaining unrepealed was article 36 ("Children born of a marriage between a member of the Imperial Family and a person not of corresponding rank, that is, not belonging to a Royal or Ruling House, shall have no right of succession to the Throne"). Aside from article 188, article 36 applied to prevent Tatiana Konstantinovna's issue from claiming succession rights.

Her contemplated marriage having been rendered legal, Tatiana Konstantinovna renounced her dynastic rights, as required. Nicholas II acknowledged this in a ukase addressed to the Imperial Senate on 9 February 1914: "Her Highness the Princess Tatiana Konstantinovna has presented to Us over Her own sign manual, a renunciation of the right to succession to the Imperial Throne of All the Russias belonging to Her as a member of the Imperial House,"[5] receiving in return Nicholas II’s authorization to marry Bagration-Mukhransky (This was the same family into which Princess Leonida Bagration of Mukhrani, wife of Vladimir Cyrillovich, was born).

Tatiana Konstantinovna and her Georgian prince were married at her father's estate at Pavlovsk, on 3 September 1911. The Emperor was present at the wedding. On the same day the Emperor issued yet another ukase, (#35766): "By Our and Grand Duke Konstantin Konstantinovich’s and Grand Duchess Elizaveta Mavrikievna’s consent, the wedding took place on 24th day of this August [old style] of the Daughter of Their Imperial Highnesses, Her Highness the Princess Tatiana Konstantinovna, with Prince Konstantin Bagration-Mukhransky. In consequence of this order: The Princess Tatiana Konstantiovna to retain the title of Highness and henceforth to bear the name of Her Highness the Princess Tatiana Konstantinovna Princess Bagration-Mukhransky..."[5]
